Description

Technical Field

[0001] The present invention relates to the technical field of bag filters, and specifically to a bag filter for combined process dust removal. Background Art

[0002] A bag filter is a very common dust removal device in the industrial production process. The bag filter sends the air containing dust into the box body of the dust collector through the air inlet pipe. The air containing dust passes through the cloth bag, and the dust therein is filtered by the cloth bag and falls into the ash hopper for collection. The air after filtration is then discharged into the atmosphere.

[0003] In the prior art, Patent CN110075626B includes a box body, several cloth bags arranged in the box body, a partition plate fixedly connected to the inner wall of the box body, an air inlet pipe arranged on one side of the box body, a fan fixedly connected to the air inlet pipe, two first shunt pipes fixedly connected to the air inlet pipe, a first connecting pipe fixedly connected to the first shunt pipe, two second shunt pipes fixedly connected to both sides of the first connecting pipe, and a second connecting pipe fixedly connected to the second shunt pipe. The box body is divided into four chambers by three partition plates. The air inlet pipe sends the air containing dust into the first shunt pipes on both sides respectively. The two first shunt pipes evenly send the air into the second shunt pipes on both sides of the first shunt pipe. The four second shunt pipes respectively send the air into the four chambers, so that the air intake of the cloth bags in the four chambers is more uniform.

[0004] However, when the existing bag filter is in use, a large amount of dust will stay on the surface of the cloth bag, affecting the filtering effect, and the dust staying inside the dust collector is difficult to remove because it adheres to the inner wall of the dust collector. Summary of the Invention

[0005] The purpose of the present invention is to provide a bag filter for combined process dust removal to solve the problems raised in the above background art.
